The father of Mohammed Emwazi, also known as Jihadi John, called his son a “dog, an animal and a terrorist.” Jihadi John beheaded numerous Western hostages of the Islamic State (ISIS/ISIL). Jassem Emwazi, 51, called his colleague on Monday to explain why he missed work at a supermarket near the Kuwait-Iraq border.

“He was very emotional and crying the whole time,” said his colleague, Abu Meshaal. “He said, ‘my son is a dog, he is an animal, a terrorist. He said he had talked to him a lot trying to persuade him to return to his personal life but that the son didn’t listen to him. He said, ‘To hell with my son’.”

Emwazi phoned his parents in 2013 from Turkey. He begged them for their blessing to join jihadist groups in Syria, but his parents exploded in anger. Emwazi drifted into Syria and became the face of the terrorist group. He beheaded hostages from America, the United Kingdom, and Japan.

“Mohammed called his father and said ‘I’m going to Syria to fight jihad, please release me and forgive me for everything’,” explained Meshaal. “Jassem said, “f*** you. I hope you die before you arrive in Syria.”

Kuwaiti authorities questioned Jassem, but he insists he is ashamed of his son. He does not want to return to work and prefers to stay at home away from the public eye.

“He said he cannot come back to work because he felt so shy of other people,” claimed Meshaal. “He is sitting home and cannot even go to the mosque to pray because he is ashamed of his son. He doesn’t want people to see him, so he is praying at home.”

Another colleague said Jassem complained he could not control his son’s behavior. He often told them his “son is not a good son.” A Kuwaiti cousin told the media the family hates Emwazi and they “hope he will be killed soon.” His mother Ghania knew it was her son when she watched one of the beheading videos. From The Daily Mail:

She was described as ‘absolutely devastated’ when she discovered he had fled to Syria, and a friend said she had been ‘crying ever since. She keeps asking her friends to pray for her son, pray for him to come back and so on.’

However, Jassem’s lawyers told NBC News there is no evidence Emwazi is Jihadi John.

“There’s no evidence this is his son,” maintained lawyer Fahd Khaled Aba Alkhail. “His face is covered. We cannot know…This is all false accusation.”
